Quality

We work according to a quality management system based on DIN EN ISO 9001:2015. We place particular importance on practical implementation and efficient, reproducible processes.

Depending on customer requirements, we create First Article Inspection Reports (FAIR) and/or carry out customer-specific assessment procedures. We successfully implemented a complex PPAP procedure for an OEM in 2015. Information for material databases (IMDS) is provided, maintained, and updated on a project-specific basis as required.

Our measuring tools are state-of-the-art and is continuously monitored. Highlights include the EOL test bench for series testing of our compressors and automated 3D coordinate measurement technology for high-precision geometry recording and documentation.

We operate our own test benches, where we test, measure, and document our compressors under real-world conditions. The testing technology is used for internal development, customer-specific approvals, and QC- EOL tests—with reproducible measurement sequences and clearly defined criteria.

Our high-speed compressor units are balanced with high precision for speeds of approx. 50,000 to 130,000 rpm and tested for concentricity and vibration behavior. In addition, we examine and validate rotor dynamic properties (stability, natural frequencies, vibration level) in short-term tests and endurance runs. To ensure reliability and robustness, we take into account realistic load collectives, thermal cycles, and long- and high-cycle fatigue (LCF, HCF).

In addition, gearbox and drive design (including torsional vibrations, efficiency, and NVH) as well as flow simulation (CFD) and geometry optimization (impeller, diffuser, volute) are incorporated into our development work. Results are documented on a project-specific basis; upon request, we provide test reports and verification documents as part of the approval process.
